17 Claims. 1

This inventionrelates to a method and` apparatus forpackaging material, the method and apparatus `being adapted to the packaging4 of dry powdered materials, granular materials, and to liquid and semi-liquid materials.

Theapparatus, as .shown in this application, is supplied with tubular box bodies in collapsed or flattened condition and. with stacks of end lclosure blanks. The apparatus operates to open or distend such bodies in their container forming condition, to form `the blanksv into flanged end closure form, and insert-and seal the same in the opposite ends of the container body, the container being lled before the second endclosure is applied;

The mai-n objectsof the invention are to provide a continuous process and a continuously operating apparatus for forming or setting up the container bodies, inserting and sealing an end closure in one `end of the body, lling the body andi then inserting and sealing the other end closure so as to produce a completed package; to provide an apparatus for effectively performing the said functionsat `a high rate of speed; to provide suchapparatus which .will be dependable in operation, andV which will requirea minimum of attention from an. operator or maintenance man.; and, in general', it is the object of the invention to provide an improved .apparatus 'and` method of the character indicated.

Other objects and advantages of the invention Will be understood by reference to the following specication and accompanying drawings (19 sheets.) vvliereinfthere is illustrated the improved method and apparatus embodying a selected form of the improved mechanism.
